The adaptive memory framework posits that human memory is an evolved cognitive feature, in which stimuli relevant to fitness are better remembered than neutral stimuli. There is now substantial evidence that processing a neutral stimulus in terms of its relevancy to an imagined ancestral survival scenario enhances recall, although there is still disagreement concerning the proximate mechanisms responsible for this effect. Several other mnemonic biases have recently been discovered that similarly appear to reflect evolutionary pressures, including a bias to remember items relevant to an imagined parenting scenario. We tested the generality of this parent processing effect by varying the biological relatedness of the imagined child. We also varied the biological relatedness of a child during an imagined third-person survival processing scenario. Across four experiments, we found evidence that simply altering the described biological relatedness of a child in the parenting scenario and third-person survival processing scenario can affect recall, such that items are better remembered when made relevant to a biological child compared to an adopted child. How these findings inform the general adaptive memory framework is discussed.

适应性记忆：亲代加工效应的普遍性和生物相关性对回忆的影响

适应性记忆框架假定人类记忆是一种进化的认知特征，其中与健康相关的刺激比中性刺激更容易记住。现在有大量证据表明，处理与想象的祖先生存场景相关的中性刺激可以增强回忆，尽管对于造成这种影响的直接机制仍存在分歧。最近发现的其他几种助记偏差似乎同样反映了进化压力，包括记忆与想象的育儿场景相关的项目的偏差。我们通过改变想象中孩子的生物学相关性来测试这种父母处理效应的普遍性。我们还在想象的第三人称生存处理场景中改变了孩子的生物学相关性。在四个实验中，我们发现证据表明，在养育场景和第三人称生存处理场景中，简单地改变所描述的孩子的生物学相关性会影响回忆，这样与亲生孩子相关的项目比收养的孩子更容易记住. 讨论了这些发现如何为一般自适应记忆框架提供信息。
